[Ubuntu-x-swat] [Bug 820881] Re: [i945] Heavy screen and font corruption on GMA950

Christian: The hypothesis of memory running low causing the problems seems to cohere with the symptoms, because for me too, the corruption appears when lots of applications have been opened for one user or many users logged in at the same time. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/820881 Title: [i945] Heavy screen and font corruption on GMA950 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/820881/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 820881] Re: [i945] Heavy screen and font corruption on GMA950
It seems the bug appears only when more than one users are simultaneously logged into the system. At least logging into system one user at time seems to help a lot in avoiding the bug. This may also be the reason why bug is not common for most users and not so easily detected (according to counter.li.org 41.67% of Linux users have only one account in their system). It also seems that bug resolves when I log all the users out and start a new session in the situation where no users are logged in. This is even a bit strange, because the screen is corrupt even in gdm login screen, which should not depend on running sessions as I (maybe incorrectly) presume. Sitsofe: I think I could test 3.0 kernel from Ubuntu Oneiric alpha Live CD. If I have time and possibility to do that on my computer, I'll try that out. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/820881 Title: [i945] Heavy screen and font corruption on GMA950 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/820881/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

It is similar or probably includes font corruption reported in https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/745608, but certain other GUI elements, for example desktop background are corrupt too.

I add the links to related pictures in another bug report.

This seemed to protect the desktop from corruption, but still corrupted the Ubuntu menu bar (see the image attached to the report).

[Ubuntu-x-swat] [Bug 745608] Re: [915GM] font corruption on Intel GMA900
Sitsofe: I reported the bug on my i945 with the desktop etc corruption at https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/820881 However I suppose the bug on my i915 is the same one as described here, because I see mainly font corruption. Window buttons are a small exception which is quite hard to notice, but this was also reported in the original bug report on i915. I believe these reports belong together, because they both consist of similar defects (extra vertical lines on small sprites). Or do you suppose there should be also separate bug report on window buttons for i915? And I want to stress that I didn't have the font corruption problem on Ubuntu 10.10 (and before), or at least it didn't happen often enough for me to notice it (although I still think I have seen it couple of times during past years). -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/745608 Title: [915GM] font corruption on Intel GMA900 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/745608/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 745608] Re: [915GM] font corruption on Intel GMA900
I installed the update package 2:2.14.0-4ubuntu7.2 from natty-proposed and it seems to make things better. At least on my laptop (915/910) I haven't noticed corruption since upgrading the package (but this may change in time, I cannot be sure). But it's different on my desktop (945), where the new package probably reduces the problem, but it still appears in previous form after some time. When I set Tiling=false it reduces corruption a lot, but there still appears some like before. Although I did notice it only in Ubuntu menu bar (submenus were fine). When I set DebugWait=true instead of Tiling=false, some of the games started doing a lot of hiccups and were practically unusable (I tried teeworlds from GetDeb). Some corruption appeared but was very episodical, by now I have noticed it only on GDM logon background image. I'd say, for me Tiling=false seemed a better workaround, because it didn't ruin the gaming experience and I didn't notice too much slowing down. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/745608 Title: [915GM] font corruption on Intel GMA900 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/745608/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 745608] Re: [915GM] font corruption on Intel GMA900
Just after writing that I noticed font corruption on my laptop (915/910) login screen. I haven't set anything in xorg.conf on my laptop though. If the corruptions have really been reduced, only time will tell, it certainly seemed so at the beginning. But they have not been removed by the new package or workarounds, that's for sure. DebugWait=true doesn't seem a viable option for me, because it renders some of the graphically more demanding programs unusable. Thanks for the efforts though.

[Ubuntu-x-swat] [Bug 745608] Re: [915GM] font corruption on Intel GMA900
I add three pictures of this bug on my 2 different computers, laptop and desktop. It seems to me that the bug often becomes effective after system has suspended and activated again or different users logging on/off the system running/killing their applications. Both systems have Ubuntu 11.04, xserver-xorg-video-intel version on both systems is 2:2.14.0-4ubuntu7.1, according to lspci desktop has 82945G/GZ and laptop has 915GM/GMS/910GML. Laptop occasionally shows slight corruption, however desktop gets heavily corrupted and this doesn't affect only fonts, as it may seem in the beginning. ** Attachment added: Slight corruption laptop.png https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/745608/+attachment/2246576/+files/Slight%20corruption%20laptop.png -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/745608 Title: [915GM] font corruption on Intel GMA900 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/745608/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
